[webkit-dev] Is there a plan for supporting multi-process and WebCL in webkit

[Oneal Bluce]

Hi Imbert,

  what you said likes what's have done in Web Workers or RiverTrail is the correct way. Now we want to make full use of the hardware computation capability on various platform, such as thin client(mobile device), PC ..etc. because now the most of the hardwares have integrate the parallel processing unit. like intel's Ivy Bridge. AMD APU and provide a more better user experience, like the 3D game on mobile device base on the Web.
 
 
Cheers,
Oneal

Hi Oneal,

Yes, leveraging multicore and the power of GPUs for general computations is great and very powerful but first, securing such kernels is hard, and authoring these would be pretty brutal to most web developers, I think this is what Benjamin was referring to.

With WebCL, you are basically writing C style kernels that you load and run to drive the computations, initiatives like RiverTrail are more restrictive but way more approachable and closer to the web, exposing higher level primitives on top of WebCL (ParallelArray for example) and integrated at the language level, which makes a lot of sense.

You can also rely on Web Workers which are now broadly available, also abstracted through libraries like Parallel.js. You won't get shared memory, but improving data passing performance between workers may be a more interesting problem to solve in the short term, with lots of value to most developers.

Hi, Benjamin 
        if browser have a capability to run some application with data-intensive parallel computing . some applications required data-intensive parallel computing can works on websit. 
 
       such as 3D movie,  3D game... etc, this can give developer a way that developer don't care which devices the application will run, this can 
shorten the application development sycle, speedup the application deployment and reduce costs.
 
maybe the browser will to be a runtime container which can provide a rumtime for those applications that have run on various OS.
   
Cheers,
Oneal

Hello, I'm a researcher and I just focusing on the multi-process supporting and WebCL supporting in browser engin. so I have some concerns about the both features. 
>In recently, Google has pronounced that they will support the multi-process in their browser egin(Blink) which is forked from the webkit. but Google will not supporting the WebCL in Blink.  so I just want to know is there a plan supporting the multi-process and WebCL in webkit.

I am very curious about the source of interest in OpenCL on browser. While OpenCL is a great technology, I have the feeling it is not ready for the web. 
What kind of applications do you foresee being powered by OpenCL on the Web?

I can imagine some use of CPU based kernels for the web (for image manipulation for example). But I have a hard time seeing how adding full support of OpenCL would not be shooting ourself in the foot at this point. That may change in the future when GPU hardware converges...

Cheers,
Benjamin
